commit c4fb60b9aba9f939d3f8575df23fd8d5958ec6ed Author: Jani Nikula <jani.nikula@intel.com> Date: Thu Jan 18 17:33:10 2018 +0200 drm/i915/bios: add DP max link rate to VBT child device struct Update VBT defs to reflect revision 216. While at it, default the expected child device struct size to sizeof the size rather than a hardcoded value. v2: Fix bit order (David) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180118153310.32437-1-jani.nikula@intel.com
Since we currently don't have any CNL machine in CI lab I can't verify that this fix works, so I can't close this bug nor archive from cibuglog. I will assign this to myself and hope that we soon get a new CNL to the lab.
fi-cnl-y2 is back in the lab, the issue is not reproduced.
